About This Gear Pump

AP2D25 / AP2D36 pump units for Komatsu PC-class and other small-to-mid excavators — compact piston pumps with the original regulator setting.

The AP2D25 is an OEM-standard aftermarket replacement built to the original mounting, spline and port specification. Bolt-on installation — no machining or adaptation required.

Every unit is inspected and pressure-checked before dispatch and ships with a test report. Stock models leave within 48 hours; non-stock units are typically ready in 5–15 days. Sea, air and express shipping are available worldwide, and our team answers quote requests within 12 hours — usually much faster on WhatsApp.

Gear pump or piston pump — which is on my machine?

Gear pumps are the compact units used for pilot, charge and small auxiliary circuits; piston pumps are the main working pumps. Tell us which circuit failed, or send a photo, and we identify it.

Are these complete units or parts?

Complete tested pump units. Internal parts (gears, shafts, bearings, seals) are available separately for the popular frames.

Can you match an old pump with no nameplate?

Yes — send clear photos of the mounting flange, the ports and the drive spline on WhatsApp. We identify from pictures every day.
